WATER- GAGE.

Specification of Letters Patent.

Patented Sept. 5, 1911.

To all 'whom it mayconcern.'

Be it known that I, FRANK J. OLEARY, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of MichiganY have invented certain new and useful Improvements in Water- .Gages of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention-relatesto water gages for steam boilers and consists kin certain provisions made in the construction of the water arm of the gage with the object in view to prevent the ball valve in said arm, which is designed to operate automatically on the breaking of the glass of the gage, from becoming inoperative by sticking to its seat due to its liming up or from corroding', all as more fully hereinafter described and shown in the accompanying drawings, in which- Figure 1 is an elevation of a Water gage provided with the improved `water arm, the same being shown in central vertical section and Fig. 2 is a vertical cross section of the water arm on line Fig. l.

Referring to the drawings A is the water' arm, B the steam arm, C the gage glass, D and E the valves controlling the admission of steam and water respectively to the gage glass and M the blow-olf having the usual blow-of cock (not shown) the parts being of the usual description and operation.

F is the ball valve inclosed in the chamber G formed in the end of the water arm below the gage glass andv communicating with the boiler through the passageH controlled by the valve E. The ball F is provided with two alternative seats for its normal support, one of these seats is formed by means of two pins or supports I projecting from opposite sides of the chamber and adapted to support the ball on opposite sides below its center of gravity and the other seat is formed by the stem ofthe valve which passes directly beneath the ball and is provided with a squared portion J.

Yportion of the stem Aagainst the downward` pressure of the steam and is also given a 'space in which it is confined. This great rolling motion at the same time within the agitation from three to six times a day as in Y the usual .practice of blowing oif that number of times prevents the ball from ever becoming limed up or stuck lfast under the 'nost unfavorable conditions.

Should the stem of the valve be rempved the pins I `will support the ball in posltion within the upper ortion of the chamber. The inner ends of t e pins are beveled at I to guide the ball in its movement and keep it centered upon the valve stem.

It is obvious` that the portion J of the valve stem may be given any other cross section adapted to impart a-lifting motion to the ball by turning the stem and the term square is intended to include all such equivalents.

What I claim as my invention is In a water gage, the combination with the water arm and its controllin valve, the stem of which passes throng the water chamber in the end of the arm, of an automatic ball valve in said chamber normally.
